La Galleria delle Applicazioni raccoglie un'ampia varietà di tutorial e di app dimostrative realizzati con COMSOL Multiphysics in diversi ambiti applicativi, inclusi quelli elettrico, meccanico, fluidico e chimico. E' possibile scaricare i file dei modelli e delle app demo pronti all'uso e le istruzioni step-by-step per costruirli, e utilizzarli come punto di partenza per le proprie simulazioni.
Lo strumento di Ricerca Rapida permette di trovare i modelli che si riferiscono alla propria area di interesse.
Si noti che molti degli esempi qui presentati sono accessibili anche tramite le Librerie delle Applicazioni incorporate nel software COMSOL Multiphysics® e disponibili dal menu File.
This tutorial shows how to simulate coupled heat and moisture transport in a wall made of a load bearing and an insulation layer. Moisture and temperature conditions vary with time on both sides of the wall and rain loading is included. The 1D model is a benchmark test defined in ... Per saperne di più
Many important processes in the mesoscale can be described by phase-field models. One of the oldest phase-field problems is the spinodal decomposition. Several standardized benchmark problems have been developed by the phase-field community. In this entry, these problems are solved using ... Per saperne di più
This model demonstrates the use of the Two-Phase Thin-Film Flow, Phase Field multiphysics coupling, which can be used to predict the evolution of an interface between two different, immiscible fluids in thin, narrow channels. The example here presents a free boundary lubrication ... Per saperne di più
This model demonstrates how to create a rotated helix geometry, i.e., a helix that is winded to form a torus. This is done sweeping a circle along a parametric curve. The radius of the torus and the radius of the coil are given as parameters as well as the number of windings of the coil. Per saperne di più
Creating irregular geometries can be a good solution, even the only option, for some types of applications. These files present a way to use a text file with material properties defined in coordinates to assign different materials even though there is only one regular domain. The same ...

The model estimates the AC breakdown voltage between parallel electrodes in air by simulating charge transport dynamics. To keep computations efficient, it is implemented in one dimension, though it can be adapted for different gases and extended to higher-dimensional setups. The ... Per saperne di più
This verification model analyzes the acoustics of two coupled rooms using the Acoustic Diffusion Equation interface of the Acoustics Module. The results of the model agree with numerical results that are validated against measurements in a reference paper. Per saperne di più
In this model, the packing behavior of grains is simulated using three force models: Hertz-MD, Hertz-MD with adhesion, Hertz-MD with adhesion and van der Waals forces. The packing efficiency is calculated to quantify the extent of packing observed. Per saperne di più
This example exemplifies the basics in how to optimize shapes using COMSOL Multiphysics®. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Designing New Structures with Shape Optimization". Per saperne di più
The Turbulent flow, Elliptic Blending R-ε interface is used to analyze fully developed turbulent flow in a spanwise rotating channel. Due to the influence of the Coriolis force on turbulence, profiles of the flow variables are skewed at moderate rotation rates. An asymmetry between the ... Per saperne di più
